Horner's method is a algorithm to divide a polynom by (x-a) ( From wikipedia:[In mathematics, Horner's method is either of two things: (i) an algorithm for calculating polynomials, which consists of transforming the monomial form into a computationally efficient form;[2] or (ii) a method for approximating the roots of a polynomial. The latter is also known as Ruffini–Horner's method.])

This program is intended for teachers or anyone who wants to grade tests or exams. It is one of the first programs that I have written, but it is constantly being improved. Version 3.5 has a better user interface, and improved control.

This is a program to create data sheets and read them. You must input a random code of 6 letters/numbers which form your personal ID. It will make secure that nobody else can read your data sheets on their calculator!

This is the Solitaire Encryption algorithm that Bruce Schneier made for Neal Stephenson's book Cryptonomicon. Before, only a TI89 version of the program existed. This is for the TI83/84s. Give your calc some time, and eventually something will come out encrypted/decrypted. The outputs are stored in Str1 and the decryption deck is stored in ∟DDECK.
